ExaCA_Temperature_test_OPENMP_np_2_nt_2 failure - only seen once, but probably indicates an unlikely race condition

Still unsure of the exact bug, but I've narrowed it down to testReadTemperatureData - some MPI ranks do not seem to store any of the appropriate temperature data (might not be reading the file at all?)

Observed an occurrence today of a similar hanging unit test, and an outright failure in checkTemperatureResults - this seemed to be Finch-ExaCA coupling specific, but could also be related
